You are welcomed!
BTW, there is a so called mega patch, which brings you directly from 4.07 to 4.10.1, including the skin patch. It has been compiled by guys from the community and may be helpfull for you in the future:

(you need to be registered on that page though, but I recommend it, as the page is awesome)
BTW: Once you are satisfied with how your game runs, you can burn it to DVDs or copy it to an external harddrive. Generally the game should run without registry entries (and maybe also without DVD), so you can place it whereever you want.
I did install my game only once - years ago - and since then I only copied/pasted it to three new computers now.
